SPECIFICATION forming part of Letters Patent No. 638,664, dated December 5, Iseo.'

Application filed January 18, 1897. Y Serial No. 619,548. lNo model.) I

T a/ZZ wiz/071e may concern.-

Be it known that I, CHARLES H. FOGG, a e citizen of the United States, residing at Hyde Park, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Heel-Compressing Machines,.of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part ro of this specification, in explaining its nature.

The invention is an improvement upon that described in the patent of Freeborn E. Raymond, 2d, and myself, dated January l2, 1897, No. 575,040; and it relates irst to means whereby a heel-compressing machine having many of the features of the machine of said application is provided with separable side dies and means for opening and closing the same and also means for feeding the heelzo blank to the said separable dies and for removing it from the same.

In the drawings, Figure l is a view in front elevation of a heel-compressing machine having the features of my invention. Fig. 2 is a view in side elevation thereof at the left side of the front. Fig. 3 is a View in horizontal section upon the dotted line 3 3 of Fig. l and in plan of parts below said line. Figs. 4 and 'are views practically upon the same 3o section, illustrating different positions of the dies and heel-blank-feeding mechanism.

The stationary head A, the heel-seat former A', carried thereby, adj ustablc vertically thereon, and removable therefrom, the man- 3 5 ner of connecting the said head with the base A2 by the rods a o a2 o3, the movable pressure-head B, movable upon the said rods, and the means for moving it are substantially like those described in the said joint applica- 4o tion, the principal difference being the employment upon the main shaft of an eccentric (connected bya link with the pressure-head B) for moving it vertically instead of a pressurecam. The upper surface h of the pressurehead B is made dat and has projecting therefrom aforward extension b', havinga at surface in continuation of the surface l). This result may be obtained by means of a sepa'- rate flat plate having the forward extension 5o fastened to the upper surface of the pressurehead B. Upon this iiat surface there are arranged two slides C C', which are movable toward and from eachother and which are attached to the pressure-head by cap-plates, the slide C having the cap-plates c c', (see 55 Fig. 4,) and the slide C having the cap-plates c2 c3. These slides operate the die-sections D D', being the sections which compress the sides and back of the heel-blank. The slide C operates the die-section D, and the slide 6o C the die-section D', and they are movable with said slides toward and from each other and are made removable therefrom that others having die-cavities of different sizes and shapes may be substituted. The slides C C are moved inward upon the upward movement of the pressure-head B by means of links, the lower or inner ends of which are pivoted to the outer ends of the slides and the upper or outer ends to stationary brackets 7o extending downward from the stationaryhead AM and either integral therewith or bolted thereto.

C2 C3 are the links connecting the slide C with the bracket C4, and C5 C6 are the links 75 connecting the slide C with the bracket C7. These links upon one side extend outward between the rods a a and upon the other side between the pair of rods a3 a2. Upon the upward movement of the pressure-head 8o B the links are straightened and force the slides C C', and consequently the die-sections which they carry, toward each other, and upon the upper surface of the pressure-head and upon the downward movement of the pressure-head the links act to move the slides outwardly upon the upper surface of the pressure-head, separating the die-sections and opening the die-cavity. This openin g extends upward from the upper surface of the pres- 9o sure-head, or, in other words, the upper surface of the pressure-head or of the plate attached thereto forms the under surface of the die-cavity, for all its sizes.

Each of the sections D D is represented as secured to its operating-slide C C in a manner to permit it to be removed therefrom, and I prefer the construction represented in Fig. 4, in which each slide is provided with a re-` cess c, having near its rear end the shoulder 10o e and at its front end the shoulder c2.

The die has a'section e3, which iits the recess of the slide between the shoulders e e2, and a rearward-extending section e4, which closes under the rear cap. A pin e5 extends through the slide from its forward face into the die, and the pin is held in place by its bent end e6, which is adapted to be turned down behind the stud c7, the stud serving to prevent the pin from working outward. To remove the die, the end e6 of the pin is moved upward and withdrawn from the die, and the forward end of the die may then be lifted from the slide and its rear end drawn from under the cap-plate. Each of the die-sections D D is thus shaped and held.

Each of the slides C C has a recessfbetween the forward end f' of the die and the incline f2 upon the slide, and the breastblock F of the die has at each end the section f3 of very nearly the shape of the said recess f-that is, it has a surface in continuation of the breast block which is adapted to be brought against the ends f of the dies-and it also has the inclinesf", against which the inclines f2 of the slides close. The closing of the said inclines f2 upon them causes the breast-block to be pushed inward by the closing of the side dies a slight distance and a practically tight joint to be obtained between the face of the breast-block and the front en ds of the die-sections D D.

The breast-block is movable upon the upper surface of the extension b inward and outward in respect to the side dies D D'. This movement is represented as imparted to it by means of the edge cam g on the camdisk G, fast to the main shaft of the machine, and the lever g', pivoted at g2, the long arm of which is connected by means of the link g3 with the said breast-block F and the short arm of which is connected to the upper end of a slide g4, the lower end of which rests against the cam g. A spring g5 coperates with the cam and acts to hold the lower edge of the slide g4 in contact with the cam. The said cam is constructed to move the breast-block inward during the beginning` of the upward movement of the pressurehead and before the slides C C have closed appreciably, and the spring withdraws it during the downward movement of the pressure-head after the slides C C have been opened sufticiently to permit the ends of the breast-block to pass by them. The breastsection F is moved outward and inward upon the extension b', and it serves to feed a heelblank placed upon said section h in front of the breast-block, or moved to such a position as hereinafter described in Fig. 4, to a position between the dies, and while they are wide open or practically wide open (see Fig. 3) and after the breast-block and heel have so been moved the side dies close upon both, forcing the breast-block toward the forward ends of the dies and against the breast of the heel by the inclines]L12 and compressing the sides of the heel, in conjunction with the former A',

mover to be moved inward, with the uncom` pressed heel-blank, between them and beyond them, or to the position represented in Fig. and to permit it to be moved in a reverse direction, and thereby remove the compressed heel from the dies and move it forward upon the plate h to a position from which it may be taken or knocked off by hand or by an uncompressed heel-blank previously placedatonesidethereof. (SeeFigs-4and5.) IVhen the compressed heel-blanlis thus dislodged or removed from said plate b', the said plate is provided with a lateral extension m, having a breast-guide m', adapted to receive an uncompressed heel-blank, which is moved thereon by hand or by a feeder IWI to a position in front of the breast-block, and in so doing the compressed heel is moved laterally upon the said plate b from in front of the breast-block over the edge m2 of the plate into trough m3 or other receptacle. IThe feeder M comprises a piece of about the width and height of a heel, preferably of metal, carried at the forward end of an arm m4, attached to the upper end m5 of a lever m6. This lever is pivoted at m7 and is moved at the required intervals by au edge cam m8 on arm or disk m9, fastened to the main shaft, and a link m10, having a cam-roll m11, which is held against the edge of said cam by a spring m12. The link is connected with the lower end of the said lever m6, and at the lower end it has a slot m13, through which passes a headed stud m14, securing it to the center of the cam in a position to permit it to slide thereon. The feeder is thus provided with a movement across the plate m, whereby it feeds an uncompressed heel-blank from said plate in front of the breast-block, and in so doing causes the uncompressed heel so fed to remove from in front of the breast-block a previously-compressed heel.

In operation the heel-blank is placed either directly in front of the breast-block when in its outermost position or in front of the feeder M, and it is fed by the breast-block between the side dies and compressed as specified and returned to be removed by hand or by the feeding of the uncompressed heel by the feeder M.

I would say that I do not conne myself to the especial devices herein described for moving the breast-block and the feeder, but'may employ in lieu thereof any mechanical equivalent.

IIO

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United Statesl. In a heel-compressing machine, the combination with the slide C having shoulders e', e2, of a removable die-section D having a portion ttiug between said shoulders and afront section extending beyond said shoulders, and a cap-plate beneath which an end of said diesection D extends.

2. The combination of the slide C having a hole, the removable die-section D also having a hole, and the die-holding pin adapted to extend through said hole in the slide into said hole in the die, said pin having its outer end bent and being adapted to be turned, and a locking-stud e7 for locking the pin in position.

3. The combination of the slides C C', the die-sections D D' carried thereby, the slides having the recesses fprovided and the inclines f2, with the breast-section F having the inclines f4 and adapted by the inclines of the slide to be moved inward slightly and its face to be brought into contact with the front ends of the die.

et. The combination of the pressure-head having the slides C C', the die-sections D D' operated by said slides, locking projections in the slides in front of said die-sections, and a breast-block having side extensions adapted to be engaged by said locking projections of said slides, substantially as described.

5. The combination of the pressure-head, dies D Dl mounted thereon and provided with closing and opening movements, with the plate b forming the bottom of the die having an extension b' a breast-block F movable upon said extension and plate and adapted to feed a heel-blank upon said extension and plate to a position between the side dies and to hold the said heel-blank in such position during the closing of said dies.

6. The combination of a pressure-head, the

opening` and closing dies D D', a breast-block YF movable toward the said `dies to feed an uncompressed heel-blank thereto, and a heelremover to move the compressed heel-blank from the dies in a forward direction, as and for the purposes set forth.

7. The combination of ,the pressure-head, the dies D D' mounted thereon and having a closing and' opening movement, the movable breast-block F and the heel-remover H connected together, the former of which is adapted to feed the heel-blank upon a level With the bottom of the die into aposition between the open dies, the heel-remover being moved between the dies and beyond them at the same time, and the heel-remover being adapted upon the opening of the dies and its return movement to move the compressed heelblank forward from the dies to its original position, as and for the purposes described.

8. The combination of the side dies D D', the movable breast-block F, the remover H both movable in relation to the said side dies as specied, and a heel-rest m at one side of the extension h' adapted to receive and hold an uncompressed heel, as and for the purposes described.

9. The combination in a heel-compressing machine of the side dies D D', the plate forming a bottom of the die and having the extension ZJ', the heel rest or support m at one side of said extension Zi', the movable breast-block F and heel-remover H connected together to be movable toward and from said dies upon the ex tension b' and plate b and the heel-feeder M adapted to move an uncompressed heel upon the support m in front of the breast F, thereby causing the uncompressed heel-blank to push a compressed heel-blank from the front of said breast into a trough or receptacle.
